Part Number: DRV8834 Tool/software: Hello,
I have a question regarding whether exceeding the VM voltage could damage the stepper motor in a DRV8834 application.
Here is the stepper motor spec:
operation voltage: 3~3.8V
operation current: 90~115mA
coil…

Hi,
We are using the DRV8834 driver and operating it at 1/2 stepping mode. There is voltage spike at Out1 whenever Out2 change state from high to low. Same observed for Out2…
Part Number: DRV8834 Tool/software: Hi TI:
we want to double check signal by datasheet.
I have captured picture from datasheet as below :
We want to check current, do you know which signal ??

Part Number: DRV8834 Tool/software: Hi team,
Does TI have phase current detect feature like TMC6200?
Could you tell me what benefit using low-side current detect or phase current? Which way is more popular? Thanks
Part Number: DRV8834 Other Parts Discussed in Thread: DRV8462 , DRV8461 Hi, I'm using DRV8834 to control a stepper motor in indexer mode without any brake system on actuator.
so some amount of current should flow on coils to hold the position in idle…
Part Number: DRV8834 Hi team,
My customer would like to see the performance of this motor driver.
Do we have a recommended motor or a motor you have used and know that it performs okay?
Thanks,
Luke
Part Number: DRV8834 Hi team,
Can you review the datasheets for:
